LG UR781 vs Samsung The Frame LS03D

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

Samsung The Frame LS03D really does well with brightness. Results at the level of 700 nits make bright elements on the screen look impressive and detailed, whether they illuminate the entire screen or appear as tiny points of light on a dark background. In more demanding scenes, like the fourth sequence from the film Sicario 2, the blacks perform moderately, but we have already discussed this in the section on contrast. However, when it comes to brightness – this television definitely holds its own. An additional advantage is the quantum dot coating, which is QLED technology. Thanks to this, the coverage of the colour palette has been improved, although The Frame does not stand out in this regard compared to the competition.

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

Samsung offers several picture modes in its televisions, but without a doubt, Filmmaker Mode is the one that should provide the most natural representation of content. Unfortunately, as often happens with mass production, the differences between individual units can be quite significant, and our tested model did not escape a few issues.

In the case of SDR content, the white balance leaned heavily towards red, with a slight boost in blue. This effect was particularly noticeable in comparison photos – for example, in a photograph of a boy whose face was unnaturally flushed. The gamma, or brightness characteristic, also did not perform perfectly – the image was slightly brightened, which robbed it of depth.

In 4K HDR content, the white balance was once again dominated by red, this time combined with green. Meanwhile, blue clearly lost intensity, which could easily be seen on the Color Checker palette, where the colours began to "escape" in the wrong direction. The EOTF curve, responsible for brightness in HDR content, showed that the television tended to overly brighten the image, particularly in the darkest elements of scenes.

Overall, while it did not look terrible, it definitely required correction. Fortunately, Samsung offers extensive calibration options, which provides a chance for a significant improvement in picture quality. Therefore, we proceeded with professional calibration to unlock the full potential of this television.

After calibration, colour reproduction in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across different scenes. The gamma has also been adjusted, providing a more precise representation of details in the shadows and bright areas of the image. As a result, the LG UR781 TV performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

After professional calibration, the Filmmaker Mode showcases its full potential. The white balance in HD content is exemplary – errors at the level of 0.5 indicate almost perfect accuracy in colour reproduction. The image now appears natural, and the colours are exactly as they should be. In 4K HDR content, the effect is not quite as perfect, but it still maintains a really high standard. The colours are vibrant, well-saturated, and the overall image quality is impressive.

So where does the problem lie, given our praise for the colour reproduction? Unfortunately, the entire experience is disrupted by the brightness characteristics. The gamma in HD content looks decent, but in 4K HDR, it’s not as good. The EOTF curve shows that the television excessively brightens certain parts of the image, which is a result of design limitations. The lack of local dimming means that the television is unable to accurately control the differences between the brightest and darkest areas of the screen. This is a barrier that simply cannot be overcome in this model.

Nonetheless, after calibration, Samsung The Frame LS03D offers excellent colour reproduction, particularly in HD content, and the overall look is significantly better than before the settings were adjusted.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

It's time to check how Samsung The Frame LS03D copes with older, lower-quality materials. We already know that the smoothness of tonal transitions is at a very high level, so we were curious to see how the TV would handle smoothing them out.

The noise reduction feature in the “Standard” setting does its job well – tonal transitions are noticeably smoothed out, and the image doesn’t lose too much detail. However, it’s worth noting that this effect also smooths out film grain, so its usage will be a matter of individual preference.

When it comes to image scaling, the TV performed really well too. The tested image came out solid – the model was accurately represented, with clear details. The branches in the background, although slightly frayed in places, generally look natural and do not stand out as a flaw.

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on a smooth, clear image without motion blur.

To start off, it’s worth noting that the model we tested in the 55-inch size, along with the 65, 75, and 85-inch versions, is equipped with a 120 Hz panel. Unfortunately, the 43 and 50-inch variants of this series only offer 60 Hz panels, which is worth considering when making a purchase. In terms of improving motion fluidity, the TV offers a feature called “Image Clarity.” This is a classic motion smoother that gives users the ability to adjust using two sliders:

Blur Reduction – this controls image sharpening during dynamic scenes. The higher the value, the less blurring occurs during fast camera moves or moving objects. However, setting it too aggressively can make the image look unnatural and resemble a “soap opera.”

Judder Reduction – this slider affects the smoothness of frame playback, especially in materials with lower frame rates, such as movies (24 fps). Higher settings can smooth out motion but can also lead to excessive “plasticity” of the image.

Both sliders operate on a scale from 0 to 10, allowing for precise adjustment of the effect to personal preferences. It’s a good idea to experiment with the settings to find the perfect balance between fluidity and a natural look for the image. We recommend setting them as shown in the picture.

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

On the positive side, the presence of a Game Bar feature allows for quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

The Frame LS03D in the 2024 version is equipped with four HDMI ports, but only one supports the 2.1 standard with a bandwidth of 40 Gb/s. This is important information if we plan to connect more than one device that requires a 4K@120 Hz signal – for example, two consoles or a console and a gaming PC.

In terms of features for gamers, The Frame truly has a lot to boast about. We have ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate) and HGiG. It’s worth mentioning that HGiG has been very well implemented here, which is particularly important as the television does not support Dolby Vision in games (which is only available on Xbox consoles). In this case, HGiG turns out to be a better standard for gaming.

Samsung hasn't forgotten about features that enhance the gaming experience. Game Bar is an expanded panel for gamers that allows quick adjustment of screen settings without having to dig through the television menu. We can even change the aspect ratio from 16:9 to the panoramic 21:9, which can be a significant advantage for some gamers.

However, Samsung's biggest ace up its sleeve is the Game Motion Plus feature. This is a special smoother dedicated to games that adds additional frames of animation without significantly affecting input lag. The effect is really noticeable – the image seems much smoother, which will be particularly appreciated by fans of dynamic titles.

In summary – Samsung The Frame LS03D is a television that offers a solid set of features for gamers. Although the limitation to one HDMI 2.1 port may be a downside, the rest of the solutions make gaming on this television a truly enjoyable experience.
